eDMSAPI tab

Note that during call handling, the eDMSAPI tab shows an overview of

current call states of each device. The window consists of two sections:

• The Jobq section contains two job queues. One jobq is for the request

from eKernel, and the other is for requests from external clients.

This area is used to temporarily store requests that are waiting to

be executed. For instance, when all the data paths are in use, new

requests must wait until resources are available.

Requests can come from the eKernel (<msgrqs>) or from an

external client (SNDNMSG|ID|DNR|MESSAGE<cr><lf> or

SNDUMSG|ID|DNR|MESSAGE<cr><lf>)

The functionality to receive requests from external clients is supported

only for the DECT Messenger application (internal use only).

• The Active section contains active jobs. This area is used to handle

currently active requests. There are three different sections in this

area: the eKernel, the External and the IoRegister.

The eKERNEL and External areas show the active extensions. Active

requests wait for acknowledge from the CSTA Service. A normal

message receives an ACK or NAK (StopDataPathRequest) reply. An

urgent message receives an initial ACK or NAK. Urgent messages

that receive ACK wait <Ack2TimeOut> seconds for a second ACK or

a NAK.
